Patent number: 11278923Abstract: A spraying apparatus includes a spraying apparatus main body, a liquid introduction portion, a gas introduction portion, a gas-liquid spout portion, a liquid inlet, a gas inlet, a tubular flow passage, a spout, a flow passage having a taper, a straightener, and a projection portion. The liquid inlet allows a liquid flow to enter a gas-liquid mixer which is a space inside the annular gas introduction portion. The gas inlet allows a gas flow to enter the gas-liquid mixer. The straightener has an opening having an uneven shape provided in the flow passage having the taper. The projection portion is provided in the liquid introduction portion, protrudes to the gas-liquid mixer, and forms the straightener and a straightening outlet.Type: GrantFiled: January 16, 2019Date of Patent: March 22, 2022Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Akira Isomi, Daisuke Tabata, Yuki Ueda

Patent number: 10866500Abstract: A projection apparatus includes a plurality of two-fluid nozzles, a projection-apparatus-side-gas-flow-path, a gas valve, a projection-apparatus-side-liquid-flow-path, a liquid valve, a projector, a mist concentration measurer, and a controller. The controller starts and stops spraying of a mist by controlling the gas valve and the liquid valve on the basis of an image or a video projected onto a screen from the projector. The controller receives a signal indicating a mist concentration from the mist concentration measurer, starts and stops spraying of the mist by controlling the gas valve and the liquid valve on the basis of the received signal, and thus controls the mist concentration.Type: GrantFiled: February 20, 2020Date of Patent: December 15, 2020Assignee: Panasonic Intellectual Property Management Co., Ltd.Inventors: Akira Isomi, Daisuke Tabata, Yuki Ueda

Patent number: 10556245Abstract: A spraying apparatus is configured such that a liquid stored in a liquid storage tank is pressurized by a liquid supplier and is supplied to a mist nozzle, so that a liquid flow is introduced from an upstream of a gas-liquid mixing section and a vicinity of a wall surface of the gas-liquid mixing section into the gas-liquid mixing section on an outer lid side. A pressurized gas is supplied from a gas supplier from a facing surface, so that a gas flow is introduced into the gas-liquid mixing section and collides with the liquid flow, and a gas-liquid mixed flow is advanced to a spout portion while circulating the wall surface of the gas-liquid mixing section on the outer lid side.Type: GrantFiled: April 20, 2018Date of Patent: February 11, 2020Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Daisuke Tabata, Akira Isomi, Yuki Ueda
